Kwek Yu Xuan was just 212g (7.47oz) – the weight of an apple – when she was born and measured 24cm long.
The baby’s mother gave birth to her by emergency C-section four months ahead of schedule after she was diagnosed with pre-eclampsia.
After spending over a year in hospital, Yu Xuan now weighs a much healthier 6.3kg (14 pounds).
The baby girl had a “limited chance of survival” according to Singapore’s National University Hospital (NUH) where she was born.
“Against the odds, with health complications present at birth, she has inspired people around her with her perseverance and growth, which makes her an extraordinary “Covid-19″ baby – a ray of hope amid turmoil,” the hospital said in a statement.
Doctors say she has progressed very well under their care and she is now well enough to be discharged.
The baby still has chronic lung disease and will need help with her breathing at home. However, NUH doctors say she is expected to get better with time.
